The shape is unique and funny, this is known as the Oreo Cookie spider, hourglass spiders are trapdoor spiders. All of them had oddly flat backs. We will tell you about the Chinese Hourglass Spider, please watch it while drinking your cup of coffee.
The Chinese Hourglass Spider is a spider in the genus Cyclocosmia genus which is famous for its trapdoor type. It is an ambush predator who is very patient waiting for prey to arrive.
If an unknowing prey ran past them, the Chinese Hourglass Spider swiftly caught it like someone opening a door. So, it is called a trap door.
Spiders can be said to be cousins of tarantulas, but they are much smaller and they do not have hairs like tarantulas. The Chinese Hourglass Spider is known for its unique and almost completely unknown belly.
All spiders in the genus Cyclocosmia have a similarity in that their stomachs are flat, but they are a different species. These spiders have a hard body structure and are difficult to penetrate, so they are safe when in the wild.
Evolution
It is thought that these trapdoor spiders have survived this tough stomach and they have expanded their belly. It has a transitional form of its belly.
Some of them are partially cut and not to the extreme as this one (Cyclocosmia). It is possible that the shape of this butt gives it an advantage in defending its life from attack by prey.
Evolution is increasingly free to tinker with the tails of these spiders and the function of their butts.
Funny facts about the Chinese Hourglass Spider:
The spider’s belly is considered to be like an ancient Chinese seal, as one farmer put it. This is also unique from the side of the buttocks, where the spider’s bottom also looks unique like an Aztec sunstone. Mmm.. it depends on how you look.
Behavior
So what are the habits of this unique spider. They are trapdoor spiders. Usually they have burrows with threads lining the ground. As soon as they detect any movement, they immediately pounce.
But if they feel threatened, they will enter the hole and cover themselves with their stomachs.
This sometimes appears to be currently fending off ants, or preventing other creatures from entering the hole. This technique used makes them very difficult to find by prey and because of this they are considered as animals that have a unique ability to survive.
Evolution side note:
Evolution sometimes likes to recycle good ideas. Turtle ants have developed a similar method to block unwanted visitors.
There are a number of species of ants and anthropods that use the same method to prevent infiltration which is known as Phragmosis.
Habitat of Chinese Hourglass Spider
Animals in the genus Cyclocosmia like to live in tropical and sub-tropical areas. Animals are found in the eastern United States, Guatemala, Mexico, Southeast Asia, East Asia and Canada.
Latusicosta species are very common in China and Vietnam. They make holes with loose soil, sandy soil, muddy soil, and the depth of the hole can be from 7 to 15 cm.
However, how is the distribution of the Chinese Hourglass Spider? Until now not known for sure. One reason is because these spiders are difficult to find, especially the males.
